/**
 * Group Base Policy (GBP) defines:
 *  - endpoints: typically a VM or container that is connected to the
 *               virtual switch/router (i.e. to VPP)
 *  - endpoint-group: (EPG) a collection of endpoints
 *  - policy: rules determining which traffic can pass between EPGs a.k.a
 *            a 'contract'
 *
 * Here, policy is implemented via an ACL.
 * EPG classification for transit packets is determined by:
 *  - source EPG: from the packet's input interface
 *  - destination EPG: from the packet's destination IP address.
